DSLAM lock; It is a limitation of internet speed. Turknet and similar companies limit this value to around 88 mbps. With the DSLAM lock, the customer is prevented from reaching higher speed. Removing this lock causes the download speed to increase and the upload speed to decrease.
It is necessary to apply to Turk Telekom for DSLAM unlocking. Turknet or other companies do not deal with this directly. If you want your speed profile to be adjusted manually, you must forward your request to the internet service provider you receive service from.
There are those who complain to Cimer when they can’t get results. It is possible to resort to this method as a last resort to reach a solution. You will receive a reply within 10 working days at the latest.
What Does DSLAM Mean?
It stands for Digital Subscriber Line Access Multiplexer . It is a network peripheral device/unit. In other words, it is a digital subscriber line access sharer. Thanks to DSLAM, DSL connection is provided to many customers on a single high-speed ATM line.
What Does DSLAM Do?
- During the use of DSLAM , signals from DSL subscribers in different regions are collected.
- These are then forwarded to a high speed network backbone (BACKBONE) line with the help of Multiplexer (MULTIPLEXER) technology.
- The DSL signal is detected by the DSLAM device.
- It defines data and voice using an ADSL modem with a POTS router.
- DSLAM receives the data; sounds are sent to PSTN.
- It is then brought to the Internet via ATM.
- The response sent to the subscriber reaches DSLAM and ADSL from ATM.
- DSLAMs to which VDSL modems are connected generate VDSL signals. The layer two protocol used by VDSL DSLAMs is EFM. It; It is known as the ‘Ethernet in First Mile’ .
- It allows to take advantage of very high bandwidth. An average of 100 Mb/s bandwidth can be provided up to 200 meters.
- The most suitable solutions for VDSL; FTTx is FTTC and FTTB.
- If the VDSL DSLAM used has 8 ports, FTTB is suitable for it. If it has more ports, FTTC application can be used.
- DSLAM multiplexers can also be connected via ATM (asynchronous transfer mode) combinations. This depends on which product is used.
DSLAM Speed Limits by Distance
DSLAM speed limit varies with distance. The following list explains this:
- 800 kbit/s at 17,000 feet (~5.2 km or ~3.2 mil)
- 5 Mbit/s at 15,000 feet (~4.5 km or ~2.8 mil)
- 16 Mbit/s at 7,000 feet (~2.1 km or ~1.33 mil)
- 19 Mbit/s at 6,000 feet (~1.8 km or ~1.14 mil)
- 21 Mbit/s at 5,000 feet (~1.5 km or ~.95 mil)
- 22 Mbit/s at 4,000 feet (~1.2 km)
- 23 Mbit/s at 3,000 feet (~900 m)
- 24 Mbit/s at 2,000 feet (~600 m)
- 25 Mbit/s at 1,000 feet (~300 m)
